Parameters List

1. Operation Mode: Perform per the settings of related control parameters
LED Display
RUN/STOP: Control setting begins. Run (
ALARM1 HIGH: Upper-limit alarm 1
ALARM1 LOW: Lower-limit alarm 1
ALARM2 HIGH: Upper-limit alarm 2
ALARM2 LOW: Lower-limit alarm 2
Setting lock: Lock 1 (
settings and Lock 2 mode only can lock others than SV value. When OFF mode is selected, the Lock
function will be OFF. If you press
the controller will be back to the previous display.
OUT: Output value display and output value adjustment in manual tuning control (This function is not
available in ON/OFF control or Auto-tuning setting)
CT: In case of using an external current transformer (CT), the controller displays the current value being
measured by CT, if the control output is ON
2. Regulation Mode: Set the control parameters
LED Display
AT: Auto-tuning setting. When AT key is set to ON (
automatically started. (PID control)
P: Proportional Band (PID control)
I: Integral Time (PID control)
D: Derivative Time (PID control)
PdoF: Offset output when P or PD control function is ON. (PID control and Ki=0)
ioF: Default value of integral volume when PID control function is ON and integral time constant is not equal
to 0(zero). AT can automatically set this parameter. (PID control and Ki≠0)
HTS: Set Heating hysteresis when ON/OFF control function is ON.
CTS: Set Cooling hysteresis when ON/OFF control function is ON.
HTPD: PID heating control cycle setting (PID control)
CLPD: PID cooling control cycle setting (PID control)
TPOF: Regulate temperature deviation value
CRHI: Regulate 20mA output deviation value (1unit = 0.1mA)
CRLO: Regulate 4mA output deviation value (1unit = 0.1mA)
3. Initial Setting Mode: Initial settings of the controller and communication parameters
LED Display
INPUT: Select input temperature sensor type
(Please refer to the contents of the "Temperature Sensor Type and Temperature Range" for detail)
UNIT: Temperature display unit,
T-HIGH: Upper limit for temperature range
